Blogging, like any marketing or networking activity is about building your brand. With lawyers and other professionals that means showing your expertise, engaging in conversations about your expertise and publishing your expertise.
Blogs allow all of this and certainly do a better job than most firm's rather static websites.
Over in America a new study by eMarketer shows a further benefit - 38% of reporters rely heavily on blogs for finding new story ideas and 29.5% use blogs to locate experts in particular fields. Reporters will search Google blogs to find an area of interest - they will then call/get in touch with the author of the blog.
This is great FREE publicity -it obviously takes time, effort and considerable patience to set up your blog, but this far outweighs the benefits.
So, if you have not yet started to blog, now is the time to consider the idea. Your name in print identifying you as an industry expert should be enough to "spur you on"!
